Domain Name System (DNS) protocols. BIND includes a DNS server (named), a
resolver library (routines for applications to use when interfacing with
DNS), and tools for verifying that the DNS server is operating correctly.
A denial of service flaw was found in the libdns library. A remote attacker
could use this flaw to send a specially-crafted DNS query to named that,
when processed, would cause named to use an excessive amount of memory, or
possibly crash. (CVE-2013-2266)
Note: This update disables the syntax checking of NAPTR (Naming Authority
Pointer) resource records.
All bind97 users are advised to upgrade to these updated packages, which
contain a patch to correct this issue. After installing the update, the
BIND daemon (named) will be restarted automatically.");
